Title says pretty much it.
To be more specific: How do you destroy this bastard WITHOUT the use of strategems (barrage, laser, rail canon strike etc.)?
Does he have any vulnerable parts on the back - like the other tanks - but they are not glowing?
How can I kill it with a auto cannon? I usually don’t carry the thermite granades.
This goes for all tanks, but the vents are not the only weak spot on them, the flat vertical plate on the back of the base of the tank is only medium armor, dump an entire amr mag in there or shoot it a few times with the quasar cannon and that bastion of savagery will go up in flames
Everyone who keeps saying shoot the vents, read the post again please. OP specified the Barrager tank, which has no vents.

OP, according to the wiki you can just shoot the top of it with Recoilless or any anti tank gun, and lacking that the rear of the body is medium armor.
Quoted from wiki: Unlike other Tank turrets, the Barrager’s MRL lacks a vent weak spot. However, the MRL itself is a large target susceptible to anti-tank weaponry such as the GR-8 Recoilless Rifle or G-123 Thermite. If a Helldiver lacks anti-tank weaponry, the rear of the Barrager’s hull can be damaged by medium armor-piercing weaponry like the AC-8 Autocannon.
Thermite throw and forget
2 shots with the Commando on the turret
Spear is also a direct kill
Auto cannon to the rear, I recommend you start carrying thermite. I made the switch a while ago it’s super useful
The back of the tank’s main body has some vents that are weak points autocannon can destroy. Although sometimes when you do that the turret survives the death of the main body and still keeps shooting. As far as I know the barrager turret itself has no weak points, so it takes anti-tank damage to kill it. They should fix both of those things IMO (the turret surviving the body’s death and having no weak points).
The weak point should be the on the back side of the turret. If I remember right you also can shoot the tracks or the back of the lower part from aside but it’s far less effective.
